Description

[0002] Powder spraying is a process of spraying powder coating to the surface of a workpiece by a powder spraying device (an electrostatic plastic spraying machine), under the action of static electricity, the powder is uniformly adsorbed on the surface of the workpiece to form a powder coating; the powder coating is leveled and solidified by high-temperature baking to become a final coating with different effects (different types of powder coating effects). In the process of powder spraying, electrostatic precipitation is one of the indispensable steps, and the ion electrostatic precipitation device is particularly important.
